Definite Integral Calculator computes definite integral of a function over an interval using numerical integration. He showed that the determination of the volume of a ball, an ellipsoid, hyperboloid and paraboloid of rotation is reduced to determining the volume cylinder. Then the problem of finding areas were formulated as the problem of “squaring a circle”: to build a square, isometric to this circle. The theorem states that if f(x) is continuous on [a,b], and F(x) is its continuous indefinate integral, then a f(x) dx= F(b) – F(a).
